How to paint while separator is moving.

[VictorN]

What are you trying to paint? In what window?

[user008]

When I moving separator window content does not changing. Content change after I released separator. I would like to update content while separator is moving.

Handle WM_SIZE in every pane you want to change some content. Use Invalidate or InvalidateRect to invalidate controls/regions you want to update - WM_PAIT (or WM_DRAW in the case of CVIew derived class) will be called automatically in response to invalidation.

Unfortunately WM_SIZE is called when lbutton is released. WM_SIZE does not called when separator is moving.

Again:

If I use Invalidate in WM_SIZE pane WM_SIZE does not call when separator is moving. Pane WM_SIZE is called when separator is released by left mouse button. I would like to call invalidate during separator is moving.

Derive your own class from CSplitterWnd and override OnDrawSplitter
